HINGE Specification oi Letters Patent.

Application filed February 20, 1909.

Patented June 29, 1909.-

Serial No. 479,152.

To all whom it may concern:

Be it known that I, OCTAVE J. THERRI- AULT, a citizen of the United States, residing at the city of Cohoes, in the county of Albany and State of New York, have invented certain new and useful Improvements in Hinges, of which the following is a specification.

My invention relates to hinges adapted for use in drying boards, and the object of my invention is to provide a hinge adapted to be placed within the adjoining parts of two leaves, whereby the mechanism shall be entirely removed from contact with the substance outside of the leaves, also a means for holding the two leaves folded together after the hinge has been opened, together with such other elements and combinations as are hereinafter more particularly set forth.

- I attain this object by means of the mechanism illustrated in the accompanying drawing, in which:

Figure 1 is a horizontal section of a portion of two leaves, with parts broken away, with dotted line showing the position during the operation of opening the hinge. Fig. 2 is a vertical section of a portion of two leaves with parts broken away. Fig. 3 is a side elevation of a portion of two leaves, with parts broken away. Fig. 4 is a front elevation of a drying board provided with my invention.

Similar letters refer to similar parts throughout the several views.

It is often desirable, for the purpose of protecting the goods placed thereon, to provide a hinge in which the operating parts are ontirely covered. This is especially the case in the use of drying boards in mills where the articles of manufacture are placed thereon in the dry room. 'When the metal parts of the hinge are exposed moisture is liable to cause rust thereon, which will be trans mitted to the goods. Where canvas or cloth hinges are used, as is often the case, they get out of order quickly and the leaves to which they are attached when the goods are taken off are in the way of the operators in the room. By my invention I do away with these objections by placing within one leaf, A, the recess, B, which is preferably cut in the end of the leaf A, and within which is secured one end of a bar, 0, by means of a bolt or nail D, or in any suitable manner. Within the adjoining leaf E is a recess, F, oppositely disposed to the recess, B, within which is placed a spiral spring, G, secured at one end within the recess, F, by means of the bolt or nail, H, or in any suitable manner, the other end of the spiral spring, G, being secured to the end of the bar, C, as at J. The resiliency of the spring acting on the bar, C, holding the two leaves, A and E, together, end to end, when in their normal position, as shown in the figures.

The block, A, is provided with a groove, K, within which a tongue, L, in the corresponding surface of the block, E, protrudes. During the operation of the hinge, as shown by dotted lines in Fig. 1, the part, E, is moved upon the tongue, L, in the groove K, elongating the spring, G, and when the surface, N, of the block, E, is in its movement brought around to engage the surface, M, of the block, A, the spring will hold the two parts A and E in engagement. In this position when the surface M of the part A is in contact with the surface N of the part E, the two leaves will be folded and out of the way, as much as possible of the operators in the room.

It is customary in using drying boards to place a shirt or other article of manufacture upon the drying board when the leaves A and E are extended, in position shown in the figures. The drying boards are then hung up on suitable supports, not shown, extending across the room, held by the ends of the leaves resting on said supports. These drying boards may be folded in the manner described and placed out of the way.

In my invention there is no possibility of the articles placed. on the drying boards coming in contact with the hinge nor any of its parts.

VJhat I claim as my invention and desire to secure by Letters Patent is:

1. The combination in a drying board, comprising two like parts; each adjoining edge provided with a recess; of a bar; a means for pivoting the same in the recess of one of said adjoining edges; a spring in the recess of the opposite adjoining edge said spring attached at one end to said bar within said recess containing the spring; a means for attaching the other end of said spring within said recess.

2. A hinge adapted to be placed in a drying board; said hinge comprising a bar with means for pivoting it and a spring a recess in one of the adjoining edges of said drying board within which said bar is secured a recess in the opposite adjoining edge of said drying board within which the spring is placed, one end of which spring is attached Within said recess to one end of said bar; a 1 In testimony whereof I have aflixed my bolt to which the opposite end of said spring signature in presence of two Witnesses.

is attached; said bolt extendin from the face r of the drying board through the recess con- 00 FAVE THERRIAULT' of said drying board engaging with a groove D. 'W. HYsoN,
